Is sleeping in a dark room better for you?
Darkness is essential to sleep. The absence of light sends a critical signal to the body that it is time to rest. Light exposure at the wrong times alters the body’s internal “sleep clock”—the biological mechanism that regulates sleep-wake cycles—in ways that interfere with both the quantity and quality of sleep.
